The Scenario

My computer is Lenovo G50 with Windows 10. It got stuck in boot loop after my windows was updated yesterday. It has a black screen with an error message saying: Install Windows. Windows could not complete the installation. To install Windows on this computer, restart the installation. When pressing OK or X boots and repeats the error message. I could get into the Windows 10 Boot menu by pressing the reset button. I tried to start in Safe Mode, but an error occurred: Can’t install Windows in Safe Mode. Any help would be appreciated, thanks.

Why is Lenovo stuck in boot loop?

Stuck in a boot loop implies that the Windows starting screen must automatically update while the boot process is still running, which results in a blank screen and no progress to the next startup step.

📸Slow lock screen/screensaver response The lockscreen and/or screensaver may be stopping the login screen from loading.
☹Unwanted applications and Windows services in the launch sequence Unwanted programs in the Windows starting sequence can occasionally cause a bottleneck.
🗂Too many startup apps During a Windows boot, there may be too many startup programs loaded.
🛠Applications that are tough to remove Some complex programs and apps, including antiviruses, might cause delayed boot times.
